A young woman named Mary is transformed into the panties by some random woman off the street. Albiet angry that she was transformed against her will, that doesn't mean that she doesn't like being worn by this. Based on the design on her new form, it's pretty apparent that she doesn't mind be wrapped around this random woman's waist.
